System Failure Codes
Occurring less frequently than condition prompts, system failure codes require the instrument to
be switched off and then powered back up. It is possible for a failure to occur due to a transient
condition. However, if the failure persists or occurs frequently, call Arizona Instrument
Customer Service at (800) 528-7411 or (602) 470-1414.
